A Butler man recounted fearing for his life when his ex-girlfriend's boyfriend, armed with a folding knife, stormed into his home in the 300 block of Fairview Avenue.

“He said, 'I'm going to kill you,'” 40-year-old Ronald Lee Schaeffer testified at John P. Conley III's preliminary hearing Monday.

Schaeffer ended up at Butler Memorial Hospital with two stab wounds — one in his arm that required 15 stitches and the other near the shoulder blade — in the Dec. 10 attack.

Butler police later that night arrested Conley at a Butler Township hotel, but not without a tussle that left a city officer injured.

District Judge William Fullerton ordered Conley to stand trial on attempted murder and other charges. He remains in the Butler County Prison on $250,000 bail.

Schaeffer said he was at his home with his 15-year-old son and an electrician doing work shortly before 8 p.m. when his former girlfriend, 26-year-old Lois Daniels, showed up.

A recent fire at Daniels' rental house had left her homeless. She came to Schaeffer for help.

“She had nowhere to go,” he testified. “She had no place to stay.”

But soon after getting there, Schaeffer heard pounding on the back door and yelling outside.

When his son opened the door, Schaeffer immediately recognized Conley, Daniels' boyfriend and someone he's had prior run-ins with, he said.

The defendant barged in with his hands in his pockets.

“I told him to take his hands out,” the alleged victim said. “We went at it and he pulled out a knife and stabbed me in the (upper) back left arm.”

He was stabbed again, he said, near the right shoulder blade.

Police described the weapon as a 3½-inch folding knife.

“It was very disturbing,” Schaeffer said. “My son had to watch me get stabbed.”

Prosecutor Laura Pitchford, a county assistant district attorney, asked him if he was scared for his life.

“Very much so,” he said. “It could have been my heart or neck.”

On cross-examination by Conley's attorney, public defender Maura Palumbi, he denied hitting her client with a steel bar.

He also told Palumbi that he suspected Conley's motive for the attack was jealousy. After the alleged stabbing, Conley and Daniels fled together, driving away in a car.

Patrolman Nicholas Shulik was called to investigate the incident. On the kitchen floor, he noticed blood, which he believed was from Schaeffer.

Police later learned that the defendant was at the Super 8 motel on Route 8 south in Butler Township and was willing to surrender.

City officers got there and placed him in handcuffs. They said they found him carrying the knife that he allegedly used to stab Schaeffer.

“The knife had blood on it,” Shulik said.

But despite having his hands cuffed behind his back, Conley continued to struggle with officers. He refused to be placed in the back of a cruiser.

Shulik said police eventually released their K-9 officer Blade, who bit Conley on at least one of his legs when he allegedly kicked the dog in the face.

Police Sgt. David Villotti, Blade's handler, in turn, tackled the suspect and forced him into the cruiser. But in doing so, police said, Villotti suffered a minor injury to his hand.

Once in the patrol car, Shulik testified, the defendant kicked at the windows. He was told to stop but refused, which prompted Shulik to deploy his Taser.

The defendant, who already had facial injuries from an unrelated assault earlier that day, was taken to Butler hospital for treatment before being placed in the county prison.

He is charged with attempted first-degree murder, aggravated assault, burglary, aggravated assault of a police officer and taunting a police animal, all felonies. He also is charged with resisting arrest.
